I have a major bike problem.
OK this is my bike
2004 ZX 6R.
1. One tooth down in the front.
2. K&N air filter.
3. Power Commander USB III
4. Micron High Mount slip on.
5. Gear indicator.
6. Vortex rear sets.
This is whatís up. So a couple weeks ago I change the oil on my bike to full synthetic and then take the bike to the track. The bike runs great at the track (ended up shaving 15 seconds off my lap time.). So the following day I take the bike out and it is running strange to say the least. So I donít think anything of it and bring the bike home. Well a couple days later I get a call from a buddy of mine and he ask if I want to head up to the mountains. Hell ya I say (I never pass up the chance to smoke a R1 on the 636, rider skill!). So we head out and I get like a mile down the road and all of a sudden BAM, the power cuts out in mid throttle and then kicks back in real hard. It was so bad it threw me forward then whipped me back on the bike. I was so surprised I ended up turning around and taking the bike home without even letting the guy I was with know. So on the way back home I noticed that every time I got to like 9000 rpms the bike would do this. It would act like I just let off the throattle then wacked back on it. So I get home and I start checking stuff.
This is what the bike does.
1. If the bike is in neutral I can rev the bike all the way to the rev limiter.
2. If the bike is in gear and Iím riding it (doesnít matter what get Iím in) the bike will hit 9000 rpms and cut out until 7500 rpms then kick back in.
3. Now when Iím not riding it (bike is on the side stand) and the bike is in gear with the clutch held in, I can rev it to 9000 rpms and it will cut out and drop to about 2500 rpms. Then it will go back to 9000 then cutout again.
4. Now when Iím not riding it (bike is on the side stand) and the bike is in gear with the clutch held in and I roll on slowly to about 8500 rpms then whack it the bike will rev past the 9000 rpm mark and hit the rev limiter.
5. Now if the bike sits over night I have to ride it for a couple miles before it will start doing this again.
So this is what I have done so fare.
1. Pulled everything off (seat, tank, and air box) and checked the wires. Nothing is burnt no lose connections nothing is unplugged.
2. Disconnected the power commander and set the bike back to stock.
3. Replaced the ECU, which cost me $800(Kawasaki told me to, they are paying me back).
4. Changed the fuel out (I wish it was just bad gas).
Now this is the bad partÖÖÖ Iím in the military stationed in Germany. The bike has been in the shop for almost a month now and the guy canít figure it out. He is a good mechanic but I think this is one of those problems that has never happened before.
This is what the shop has done.
1. Checked the side stand switch. Thatís fine.
2. Checked the neutral switch. Thatís fine.
3. Checked to make sure the fuel tank is venting right. All good there. Checked the power commander. Itís ok.
Does anyone have any idea what is wrong with my bike? And please donít give me the stupid ďItís a KawasakiĒ crap. If you canít help then either donít post or just say you canít help.
Any info would be great!
